Answer:
21 because there is a 1/4 chance and there are 84 questions, so 1/4 (25%) of 84 is 21.
Step-by-step explanation:
Answer:
So we know the formula to calculate the area of the circular sector:
S=(r^2*π*a)/306°=
(5^2*3.14*40°)/360°= (1000*3.14) /360=8.72cm^2 so the right alternative should be the first one ,A.
Step-by-step explanation:
r - radius of the circle
a - corner of the circular sector
S - surface
If you're asking the difference between 14 ft and 21 ft your answer is 7 ft, just subtract 14 from 21
You combine both 2x-12 and x+2 and 11 which makes the equation
2x-12+x+2= 11
The you get your answer which is
X=7
